I posted a new script over at VASST. I've used this for a long time and find it really useful.
Fade this event AND the event on the track below (audio) to black. Fade length is set using distance from cursor position to end of event that is under the cursor on the first selected track. If there is an audio track under the selected track, it is also faded. If the track below is not audio, nothing is done to that track.
Fade In/Out at Cursor
